Solution

The correct option is C The particles present in the atmosphere scatter orange color mostly.
The color of sky is mainly due to the scattering of the light. Scattering depends upon the size of the particles so if we can change the size of all the particles present in the atmosphere we can also change the color of the sky and as that planet’s sky is orange that means that the particles in its atmosphere are scattering orange light mostly.
